On the form load, the grid is loaded with three parts. Upon refresh, the buttons call a method which generates the same data table but with some additional parts - to simulate a data refresh.

Button 1 - Refresh Data
- This button calls a method that operates the same as detailed initially in the ticket; it utilizes the BeginUpdate/EndUpdate methods around the updating of the grid. This replicates the scenario I initially described where message boxes are fired stating "Column 'xxx' does not belong to table 'fileSystem'.".

Button 2 - Refresh Data 2
- This button calls a method that is modified as suggested - the BeginUpdate/EndUpdate methods have been removed and the DataSource is set directly.

Button 3 - Clear Data
- This button is meant to simply clear the data from the grid. It only attempts to set the DataSource property to Nothing.
